6 Augustus places Tigranes’ brother =Artavasdes II= on the Armenian throne. 5 Tigranes recovers his kingdom. Both kings seem to rule simultaneously. They are finally driven out. 2 =Ariobazanes= or, according to some historians, =Tigranes IV (V)= is placed by Augustus on the disputed throne. He may have been a Mede or perhaps an Armenian exile. A.D. 2 Death of Ariobazanes. =Erato=, probably widow of Tigranes III (IV), succeeds. 4 According to Armenian historians a son of Ariobazanes (Artavasdes III) takes the throne from Erato, but she regains it in a few months. After Erato’s death or deposition (date uncertain) and a short interregnum, 16 =Vonones= the exiled monarch of Parthia is chosen king, but Tiberius persuades him to retire to Syria. 18 =Artaxias III= chosen king after a short interregnum. He is succeeded by (date unknown) =Arsaces I=, placed on the throne by his father Artabanus III of Parthia. 35 Death of Arsaces through treachery of Mithridates, brother of Pharasmanes king of Iberia. =Mithridates= invades Armenia, and Tiberius gives him the throne. Caligula summons him to Rome, imprisons him, but restores him about 47. 52 Mithridates slain by his nephew =Rhadamistus= of Iberia. 54 Vologases I of Parthia expels Rhadamistus and makes his own brother =Tiridates I= king. 58 Corbulo drives out Tiridates I and puts Tigranes V (VI) Herodes the Cappadocian on the throne. 61 Vologases crowns Tiridates king of Armenia and proceeds against Tigranes. 66 Tiridates goes to Rome to receive the crown as a gift from Nero. Meanwhile, =Erorant=, of the younger Arsacid branch, has established himself, about 58, over a large portion of Armenia. He is the contemporary of Tiridates, and after the latter’s death, probably rules the whole country. He cedes Edessa and Mesopotamia to the Romans. 78 =Exeardes=, son of Pacorus II of Parthia, is appointed to the throne. He is several times driven out, but always manages to recover his throne. 112 Osroes, brother of Mithridates VI of Parthia, expels Exeardes and makes =Parthamasiris=, another son of Pacorus, king, for which act Trajan invades Armenia. Parthamasiris is humbled. 117 Trajan appoints =Parthamaspates=, son of Oroes, king. He is expelled, and recovers the kingdom from Hadrian. He is succeeded by his son, =Achæmenides=, and he in turn by =Soemus= or =Sohæmus=. 162 Vologases III of Parthia expels Sohæmus, who is friendly to Rome, and makes =Pacorus= king. 163 or 164 Sohæmus restored by the Romans, and is succeeded (date unknown) by his son, =Sanatruces= or =Sanadrug=, who is established on the throne by Septimius Severus. 212 Caracalla seizes Sanatruces.
